今天闲来无事，写了一个数组分页函数，分享给大家，还不是特别完善，函数很简单，有很大的空间可以自由发挥~~~
函数体：
/*
* @array 所有数据
* @start_page 开始页数
* @page_size 每页数量
*/
function array_page($array,$start_page=1,$page_size=5) {
$array_count = count($array); //数据总数
$page_count = ceil($array_count/$page_size); //总页数
$start_page = ($start_page < $page_count) ? $start_page : $page_count; //保证接收来的$start_page在合法的范围内
$prev = (($start_page - 1) > 0) ? ($start_page - 1) : 1; //上一页
$next = (($start_page + 1) <= $page_count) ? ($start_page + 1) : $page_count; //下一页
$return_array=array_slice($array,($start_page-1) * $page_size,$page_size); //当前页面显示的数据
$page="当前第{$start_page}页<a href='?page=1'>首页</a> <a href='?page={$prev}'>上一页</a> <a href='?page={$next}'>下一页</a> <a href='?page={$page_count}'>尾页</a> 总{$page_count}页";
$return = array('content'=>$return_array,'page'=>$page); //content当前页面显示的内容,page分页
return $return;
}
调用实例：
$array=array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20"); //所有数据
$start_page = isset($_GET['page'])?$_GET['page']:1; //当前页
$page_size = 3; //每页显示3条数据
$return = array_page($array,$start_page,$page_size);
foreach($return['content'] as $content){
echo $content . '<br>';
}
echo '<hr>';
echo $return['page'];
